Indiana Jones had it all wrong

I saw these little beauties just before going for dinner. My magpie heart leapt. Skulltastically gorgeous ... a must have ... If only Indiana Jones had cashed in his chips and had dinner in Princes Square ... he could have saved himself a bruise or two with these crystal skulls. Mind you ... he would have had to pay through the nose for these ...

I wonder what Arthur C Clarke would have made of them ...
